REFRIGERATING UNIT.

Application led August 11, 19,27. Serial No. 212,253..

The invention relates to refrigerators of the compressor type and hasreference more particularly to the heat-absorbing unit in which theusual boiling action of the refrig- 5 erant takes place, said unit beingprovided With means to receive pans for freezing Water or other fluids.

It is the object of the invention to provide ay new and improved,exceptionally simple l0 and inexpensive and very eiiicient refrigeratingunit in which ai plurality of shells which receive the fluid-freezingpans, are substan tially surrounded by the refrigerant so as to obtainmaximum efliciency and at the same l5 time permit the use of a smallerquantity of'refrigerant than canv ordinarily be used, this being notonly of advantage for economy in chargingthe apparatus, butin case ofany leaks, as Iless of the refrigerant can run from the apparatus thanif more were used.

Withthe'foregoing in View, the invention resides in the novel subjectmatter hereinafter described and claimed, the description beingsupplemented by the accompanyingr drawing. y l

Fig. 1 is a vertical sectional view through a refrigerating unitconstructed in` accordance With my invention, showing it operativelyconnected with the usual float tank, to which the liquid refrigerant ispumped and from which the gas generated by the boiling of the liquid, isdrawn. l

Fig. 2 is a vertical transverse sectional view on line 2 2 of'Fig. 1.-

application and While this construction will be herein specificallydescribed,.it is to be' understood that Within the scope of theinvention as claimed, variations may be made'. In the drawing abovebriefly described, the

numeral 3 designates an outer shell for the re-- The preferred form ofconstruction lhas been selected for illustration in the present ply tube13 leads to said valve, and a gas dis charge tube 14 leads from theupper portion of the tank. The float-controlled valve 11 controls thellevel of liquid in the tank 8 in 55 the usual manner, this liquid ofcourse also fills the shell 3 through the communicating nipples, theboiling of the liquid takes placel in said shell, the gas rises throughthe communicating nipples 'into the upper portion of 50 the tank 8, andsaid gas is pumped olf through the tube 14.

The front end'of the outer shell 3 is open and is provided with anintegral outstanding flange 15 to Which a removable front 'Wall 16 65 issecured by bolts 17, an appropriate gasket 18 being interposed betweensaid flange and Wall. At suitable locations, the front Wall 16 is formedwith openings 19 through which to insert theusual fluidfreezing pans(not shown). This front wall carries a plurality of inner shells 20preferably of rectangular form, said shells having open front ends andbeing at said ends integrally joined to said front Wall around theopenings 19, said shells 76 Abeing adapted-to receive the fluid-freezingpans. These shells are spaced from all walls of the outer shell 3 Withthe exception of the front Walll and they are also lspaced from eachother, so that each of them may be so substantially surrounded by therefrigerant to obtain unusual efficiency, making it possible to freeze-Water, custards, etc., in a shorter period of time than is noWpossible.

.. In case repairs should be necessary to one 35 I ,of the shells v2Oorto the shell 3, the plate 16 may be unbolted from the shell 3,'permitting all of the shells 2O and said plate 16 to be removed as asingle unit from' the shell 3, thus giving access to the interiorofshell 3 or to the 'exterior's of the shells 20, as may be required.

'Attention is again invited to the fact *hat While the preferred form ofconstruction has been shown and specifically described,` variations maybe made Within the scope of the inventionas claimed.

A refrigerating unit comprising an outer shellto contain a refrigerant,said shell being provided With externall heat-conducting:,ns, with anipple at its top for connection with a float tank, and with aremovablefront wall,

the latter being formed vwith spaced openings through which to insertfluid-freezing pans, and a pluralit of inner pan-receiving shells havingopen ront ends integrally joined to said front Wall and communicatingWith said openings, said pan-receiving shells being spaced from allother Walls of said outer shell and from each other, permitting eachinner shell to be substantially surrounded by the refrigerant.

In testimony whereof I have hereunto affixed my signatnre. v
